Winergy’s HybridDrive wins 2013 Product Differentiation Excellence Award

By Michelle DiFrangia | March 11, 2014

The award-winning HybridDrive combines a two-stage planetary gearbox with a permanent magnet-generator into an integrated drivetrain.

The award-winning HybridDrive combines a two-stage planetary gearbox with a permanent magnet-generator into an integrated drivetrain.

Based on its recent analysis of gearboxes for the wind energy market, the global research organization Frost & Sullivan awarded the 2013 Global Product Differentiation Excellence Award to Winergy’s HybridDrive due to its higher torque–to-weight ratio, shorter length, and lower mass leading to reduced overall costs for the wind turbine installation.

Winergy’s HybridDrive combines a two-stage-planetary gearbox with a permanent-magnet-generator into an integrated drivetrain resulting in length reduction of 35 to 50% for the entire drivetrain. The system has a power transmission efficiency of more than 96.5%, thus decreasing the weight of the drivetrain up to 10% for larger turbines.

“By decreasing the mass and increasing the torque-to-weight ratio of the drivetrain, HybridDrive has resolved the issue of the inverse correlation between ROIs and power capacities of a wind turbine,” says Krishna Raman, a Frost & Sullivan research analyst.

Customers of the HybridDrive can choose between journal bearings and standard anti-friction bearings, whereas the former results in less abrasion and an increase of the wind turbine’s availability.

Winergy sets a milestone in the development of wind turbine drivetrains with the Hybrid Drive. Since October 2013, the 3 MW HybridDrive has been installed in a Wind-to-Energy (W2E) turbine in northern Germany and has produced more than 4 million kWh.
